What is a susu? West African and Caribbean savings explained
By Tyknit · Published 2026-08-27
A susu (also sou-sou, esusu, or ajo) is a rotating savings club with roots in West Africa and the Caribbean: a fixed group of people each pay a set amount into a pot on a schedule, and every member receives the whole pot once per rotation.
One idea, many names
The Yoruba esusu and ajo, the Igbo isusu, the Akan susu, the Trinidadian and Caribbean sou-sou, the Jamaican partner and the Bahamian asue are all the same mechanism carried across the Atlantic and adapted. In Ghana alone the Bank of Ghana licenses thousands of susu collectors. In the diaspora — London, New York, Toronto — susus remain one of the most common ways West African and Caribbean families save for school fees, a deposit, or a trip home.
How the rotation works
Ten members agree to pay 100 each week. Every week one member “draws the hand” — receives the full 1,000 — until all ten have drawn, after which the group either dissolves or starts again. The order can be fixed by lot, by agreement, or by need; the first draws are effectively an interest-free loan and the last are pure savings. No interest is charged or earned, which is one reason susus are popular among people who avoid interest for religious reasons.
The collector model
In Ghana and Nigeria a distinct form exists: the susu collector, a licensed individual who visits traders daily, collects a small fixed deposit, and returns the month’s total minus one day’s deposit as a fee. This is a savings service rather than a rotation, and it is increasingly regulated and digitised.
Where susus break
The rotation has one structural weakness: a member who draws early and then stops paying has borrowed from everyone else. Groups manage this by putting the least-trusted members last, by demanding a guarantor for newcomers, and by keeping the group small enough that everyone knows everyone. A written record of every payment, visible to all members, turns a dispute from memory against memory into a matter of fact.
Susus and Tyknit
Tyknit supports rotating pools directly: a schedule, a visible ledger of who has paid and who has drawn, vouched admission with a sponsor who answers for a newcomer, and payouts recorded on the group’s own rail — cash, bank, or mobile money — because Tyknit never holds the money.
